Figure' 4 isa fragmentary horizontal sectional view, taken substantially` along a line 4-4 of Figure 1, and y Figure 5, is a fragmentary vertical sectional view of the register', taken substantially along a plane as indicated by the line 5-5 of Figure 4. i

Referring morespecically to the drawings, the lcoinbination hot and cold air Abaseboard register in its Ientiretyv is designated generally 7 and is composed of an intermediate section, designated generally 8, and end sections designated generally`l9 and 10. Each of the register sectionsis formed of sheet metal.

The intermediate section 8 is composed of two'strips of sheet metal one of whichs'trips forms the rear 4part of the registersection 8 and which includes a rear wall 11, a horizontal partition wall 12, a bottom wall 13 and a front flange 14. The partitionwall 12, which is dis-` posed above an'd spaced from'fthebottorn' 13, constitutes a forwardly extending'lapped two-ply portion of the rear wall 11. The parts 11, 12, 13 and 14 extend from endto-end of the intermediate sectiony 8. A second elongated piece of sheet metal Iforms the front and top of the register section 8 and is of the same length as the piece forming the parts 11 to A14A and includes" a lower-portion forming the front wall 15 Vof the register section'8` A bottom longitudinal edge portion of th front wall 15 'bears against andis suitablysecured as'b'y welding, as se'en at 16, toltheflouterV side ofthe upturned flange 14. The front part -ofthe register section 8 includes an inclined top vwall 17 which extends upwardly and rearwardly at plane as indicated by *the 2,868,103 Y Ptented Jan. v13, 19.59

2; an incline from the upper edge of the front wall 15 and has a downtur'ned flange 18 at the upper edge thereof which bears against the outer side of the upper portion'4 of the rear wall 11. The parts 15, 17 and 18, all of. which are formed from the second strip of metal,V each extends from end-to-endv of the register sectionS.' The4 upper portion of the front wall 15 is provided with a.- plurality of struck-out portions formingopenings 19 Vand externally disposed upwardly opening louvers '20, .which communicate with said openings 19 and which open upwardly and outwardly of the register 7. 'The louvers4 2t) land openings 19 are disposed in vertically spacedVA Iapart relation to one anotheigas seen in Figures 1 and 3, and said lfront wall 15 mayube provided with a pluf;l rality of longitudinally spacedl sets of said openings'and, louvers, depending upon the length thereof. The lowerY portion of the front wall 15 is also provided with` struck-Y out portions forming openings 21 and louvers 22, cor. responding to the openings 19 and louvers20, except thatJ the lower louvers V22` open downwardly instead ofi upwardly, as clearly illustrated in Figure 3. The open-, ings 19 and louvers 20l are disposed above the level of: the partitio-nhwall 12, and the openings 21 and louvers 22 are disposeddbelow the level of said partition Wall..

Theopenends of the intermediate section 8 are closed by the end sections 9 `and 10 which telescopically engage over saidr open ends, `andlwhich may be'extended or re-r tracted to vary the over-all length of the register 7. Each end section 9 and 10, as best illustrated in Figures 2, 4 and 5, includes a substantially iiat upright rear wall 23,4 an outer end wall 24 and a front -ange 25, which parts are formed from a single piece of sheet metal. The end `wall V24 is disposed at rightangles to the rear wall 23. and `flange y25, and` said rearvwall and flange extendinthe same direction -frompthe end wall 24. The end wall 24 has,V an inclined upper edge V26, the lowerend of which is disposed above the level of the upper end ofY the front flange 25. Each end section 9 and 10 alsof includes an upright front wall 27, an inclined top wall- 28 and a flange H29 forming a downturnedexten'sionoft the upperSedge Aofpthetopwall 28 and whichl engages the? upper portionot the outer side of the rear wall 23. The part-s 27, 28 and 2,9 are Iformed from a single piece of sheet metal and` the outer end of the inclined top-wall 28 bears against the inclined upper edge 26 of the endy wall 24.* The outer edge of thefront wall 27 -bears` against theouter side of the front ange 25 and isse-v cured thereto, as by welding, as seen at 30. `i Each end section 9 and 10 also includes an upper partition 31 and a lower partition 32, each of which is formedfrom a strip of sheet metal. The partitions 31: and 32 have complementary upturned ends ,33 and 34, respectively, which are disposed` against the inner side of the end wall 24 and which are secured thereto, as byv additional welds 35. The` partitions 31 and 32, extend to the inner open end of thel end section andare of al 'l Widthless than the spacing between the rear wall 23 and fronttwall 27,and have their side edges spaced slightly from said walls. Said partitions 31 and 32 are offset upwardly4 slightlyrelative to the partition 12 and bottom 13` of the intermediate section 8, respectively, so :as

`than the height of the rear wall 11, so that the endsec'-v 3 tions 9 and 10 are sized to lit over the ends of the intermedi-ate section 8.

The assembled register 7, as seen in Figure 1, is adapted to rest on a oor 37 and with the upright back side of the register disposed against the lower portion of an upright wall 38, in the same manner that a baseboard is secured to the corner formed by a oor and wall. The end sections 9 and 10 are extended or retracted to locate one end section over the discharge end of a hot air duct 39, which extends upwardly throughthe oor 37, adjacent the wall 38, and to locate the other end section directly over the open inlet end of a cold air duct 40, which also extends upwardly through the floor 37, adjacent the wall 38. As illustrated in Figures 2 to 5, the endy section 9 is located in vertical alignment with the hot air duct 39. The partitions 31 and 32 thereof are provided with knockouts which are removed to form openings 31 and 32', respectively, therein through which the upper portion of the hot air duct 39 extends, so that the discharge end ofthe hot air duct opens above and adjacent the partition 31 of the end section 9. The knockout of the bottom partition 32 only of the other end section 10 is removed to provide an opening 32 through which the upper portion of the cold air duct 40 extends and so that the inlet end of said cold air duct is located immediately above said lower partition 32 of the section 10. The knockout 41 of the upper partition 31 of the section 10 is not removed so that the chamber 42 of the register 7, which is disposed above the partitions 12 and 31, is closed oi from the lower chamber 43, which is disposed heneath said partitions 12 and 31, Said chambers 42 and 43 extend from end-to-end of the register 7. If the ducts 39 and 40 are suiciently large in size so as to substantially correspond to the spacing between the rear walls 23 and front walls 27, the partitions 31 and 32 of the end section 9 could be removed entirely to accommodate the hot air duct 39 and the lower partition 32 of the end section 10 could be entirely removed to accommodate the inlet end of the cold air duct 40.

Assuming that the register 7 is assembled and positioned as illustrated in the drawings relative to the oor 37 and wall 38- and connected to the hot air duct 39 and cold air duct 40 as previously described and as illustrated, hot air from a heating system, not shown, would be supplied under pressure through the hot air duct 39 and will be discharged therefrom into the upper register chamber 42 from which the Iair will escape into the enclosure or room, of which the oor 37 and wall 38 form parts, through the openings 19 and the upwardly opening louvers 20. The hot air will thus be discharged upwardly away from the floor. At the same time, a suction will be created in the cold air duct 40 and, in turn, in the lower cold air chamber 43 of the register 7, so that cold air, adjacent the floor, will be drawn upwardly into the downwardly open louvers 22 and will enter the cold air chamber 43 through the openings 21 and will be withdrawn from the register through the cold air duct 40.

It will thus be apparent that the combination hot and cold air baseboard register 7 is adapted to be connected to both a hot air duct and a cold return duct for simultaneously supplying hot air to an enclosure and -for extracting cold air therefrom.

Various modifications and changes are contemplated and may be resorted to, without departing from the function or scopeof the invention as hereinafter dened by the appended claims.
